from my experiences i'd say both are necessary. you beat your arms up one way or the other, and for the most part i focus on form more than weight. but once in a while, maybe once a month or so, i go pretty heavy and swing if necessary just to push myself

DB + BB curls I swing a bit, heavy weight gives me the best pumps and feels like it recruits more fibraz. Arnie's fave exercise was BB cheat curls if I remember rightly

Finish that shyt off with super controlled preacher curls and my bis are screaming for mercy

OP's saying increase weight and don't worry about strict form ie. swing the weight up
